Remarks

When used in the main prose of a document, the mark element indicates a part of the document that has been highlighted. When used in a quotation or other block of text (such as an aside), it indicates a highlight that was not originally present but which has been added to bring the reader's attention to a part of the text. For example, the following are valid uses for the mark element:

Bring attention to a particular string of text.
Highlight parts of document that match a search string.
Enable body text to refer to a specific part of a quotation or code fragment.

The mark element is only supported for webpages displayed in a Windows Store app using JavaScript. For more information, see Defining Document Compatibility.

The mark element denotes the relevance of a span of text. To indicate importance, use strong or em.

The default CSS for the mark element is:


color: black;
background-color: yellow;

Examples

The following example shows the difference between denoting the importance of a span of text (strong) as opposed to denoting the relevance of a span of text (mark). It is an extract from a textbook, where the extract has had the parts relevant to the exam highlighted. The safety warnings, important though they may be, are not relevant to the exam.


<h3>Wormhole Physics Introduction</h3>
<p><mark>A wormhole in normal conditions can be held open for a
maximum of just under 39 minutes.</mark> Conditions that can increase
the time include a powerful energy source coupled to one or both of
the gates connecting the wormhole, and a large gravity well (such as a
black hole).</p>
<p><mark>Momentum is preserved across the wormhole. Electromagnetic
radiation can travel in both directions through a wormhole,
but matter cannot.</mark></p>
<p>When a wormhole is created, a vortex normally forms.
<strong>Warning: The vortex caused by the wormhole opening will
annihilate anything in its path.</strong> Vortexes can be avoided when
using sufficiently advanced dialing technology.</p>
<p><mark>An obstruction in a gate will prevent it from accepting a
wormhole connection.</mark></p>
